Pamusoro peiyo yakakwidziridzwa mhedzisiro yekufambisa simba uye antenna kuwana pasimba rechiratidzo, kurasikirwa kwenzira, zvipingamupinyi, kupindira uye ruzha zvinoderedza simba rechiratidzo, izvo zvese zvinopera chiratidzo.Kana kugadzira arefu siyana network network, isu tinofanirwa kuderedza kupera kwechiratidzo uye kukanganisa, kuvandudza simba rechiratidzo, uye kuwedzera chinhambwe chekufambisa kwemasaini.
Signal Fading
Simba rechiratidzo chewireless richaderera zvishoma nezvishoma panguva yekufambisa.Sezvo anogamuchira achigona chete kugamuchira uye kuona masaini masaini ane simba rechiratidzo riri pamusoro pechimwe chikumbaridzo, kana chiratidzo chidiki chakanyanya kukura, mugamuchiri haakwanise kuchizivisa.Izvi zvinotevera zvinhu zvina zvikuru zvinokanganisa kudzima kwechiratidzo.
● Chipingamupinyi
Zvipingamupinyi ndizvo zvinowanzoitika uye zvakakosha mumhepo isina waya yekutaurirana ine mhedzisiro yakakosha pakudzikamisa chiratidzo.Semuenzaniso, madziro akasiyana-siyana, magirazi, uye magonhi zvinoremesa masaini mawaya kusvika padanho rakasiyana.Kunyanya zvipingamupinyi zvesimbi zvinogona kuvhara zvachose uye kuratidza kupararira kwemasaini masaini.Naizvozvo, kana tichishandisa maredhiyo asina waya, tinofanira kuedza kudzivirira zvipingamupinyi kuti tiwane kutaurirana kwakareba.
● Kuendesa kure
Kana mafungu emagetsi achipararira mumhepo, sezvo kureba kwekufambisa kunowedzera, simba rechiratidzo rinopera zvishoma nezvishoma kusvika ranyangarika.Iyo yekudzikisira panzira yekutapurirana ndiyo kurasikirwa kwenzira.Vanhu havagone kushandura kukosha kwekudzikisa kwemhepo, uye havakwanise kudzivirira masaini emhepo anofambiswa nemhepo, asi vanogona kuwedzera nhambwe yekufambisa kwemafungu emagetsi nekuwedzera zvine mutsindo simba rekutumira uye kuderedza zvipingamupinyi.Iyo imwezve magetsi emagetsi mafungu anogona kufamba, nzvimbo yakafara iyo isina waya yekufambisa system inogona kuvhara.
● Kakawanda
Kune masaisai emagetsi, kupfupika kwewavelength, ndiko kunyanya kudzikama.Kana iyo frequency yekushanda iri 2.4GHz, 5GHz kana 6GHz, nekuti frequency yavo yakanyanya kukwirira uye wavelength ipfupi, kupera kunenge kuri pachena, saka kazhinji kureba kwekutaurirana hakuzove kure.
Pamusoro pezvinhu zviri pamusoro apa, senge antenna, chiyero chekufambisa data, modulation scheme, nezvimwe, zvichakanganisawo kudzima kwechiratidzo.Kuti tiite nhambwe yakareba yekutaurirana chinhambwe, mazhinji eIWAVE isina waya data transmitterinotora 800Mhz uye 1.4Ghz yeHD vhidhiyo, izwi, kudzora data uye TCPIP/UDP kufambisa data.Iwo anoshandiswa zvakanyanya kune drones, UAV mhinduro, UGV, kuraira kutaurirana mota uye tactical ruoko rwakabata radio transceiver yakaoma uye kupfuura mutsara wekuona kutaurirana.
●Kupindira
Pamusoro pechiratidzo chekudzikisira chinokanganisa kucherechedzwa kweanogamuchira masaini masaini, kupindira uye ruzha zvinogona zvakare kuve nemhedzisiro.Chiratidzo-ku-ruzha reshiyo kana chiratidzo-ku-kukanganisa-kune-ruzha reshiyo inowanzoshandiswa kuyera kukanganisa kwekukanganisa uye ruzha pamasaini asina waya.Chiratidzo-ku-ruzha reshiyo uye chiratidzo-ku-kupindira-kune-ruzha reshiyo ndiyo huru yehunyanzvi zviratidzo zvekuyera kuvimbika kwehutano hwekutaurirana kwehurongwa hwekutaurirana.Iyo yakakura reshiyo, zviri nani.
Kukanganisika kunoreva kukanganiswa kunokonzerwa nehurongwa pachahwo uye masisitimu akasiyana, senge-mwe-chaneru kupindira uye kukanganisa kwakawanda.
Noise inoreva mamwe masaini ekuwedzera asina kujairika muchiratidzo chekutanga chinogadzirwa mushure mekupfuura nemumidziyo.Ichi chiratidzo chine hukama nenharaunda uye hachinje nekushandurwa kwechiratidzo chepakutanga.
Signal-to-noise ratio SNR (Signal-to-noise Ratio) zvinoreva chiyero chechiratidzo kune ruzha muhurongwa.
Chirevo chechiratidzo-ku-ruzha reshiyo ndechekuti:
SNR = 10lg (PS/PN), uko:
SNR: chiratidzo-kune-ruzha reshiyo, unit iri dB.
PS: Simba rinoshanda rechiratidzo.
PN: Simba rinoshanda reruzha.
SINR (Signal to Interference plus Noise Ratio) zvinoreva chiyero chechiratidzo kusvika kuhuwandu hwekuvhiringidza uye ruzha muhurongwa.
Chirevo chechiratidzo-ku-kupindira-kune-ruzha chiyero ndechekuti:
SINR = 10lg[PS/(PI + PN)], apo:
SINR: Chiratidzo-ku-kupindira-kune-ruzha chiyero, iyo unit iri dB.
PS: Simba rinoshanda rechiratidzo.
PI: Simba rinoshanda rechiratidzo chinopindira.
PN: Simba rinoshanda reruzha.
Paunenge uchironga nekugadzira network, kana pasina zvakakosha zvinodiwa zveSNR kana SINR, zvinogona kuregererwa kwenguva pfupi.Kana zvichidikanwa, paunenge uchiitisa simba remumunda simulation mukuronga kwetiweki dhizaini, chiratidzo chekupindira-kune-ruzha reshiyo simulation ichaitwa panguva imwe chete.
